TO WI-IOM IT MAY CONCERN:

ABe it known that I, ROBERT HOWDON, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Mede of Securing Wooden and other Objects to Metallieand other Surfaces; andI hereby'declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part ot' this specification. y 'v This invention relates to a mode of securing ornaments-:or other objects of wood7 papier mache, or like material to metallic or other surfaces. I

Figures l and 2 are longitudinal and' transverse sections representing a portion of a. coilin.

Figure 3 is a transverse section showing a modification of my invention.

A represents a portion of a metallic coiin or other article of metal or like material. B represents a strip ot` wooden moulding, which may be encased with gold or silver plate 6. C are doubly countersunk holes inthe metallic ease or other article. D -are diverging holes bored in the back of the moulding. The moulding being hold in place with its back tothe metallic surface I pour through the holes C and into the holes D in communication, a metallic alloy, capable of fusing at a temperature .that will not Aby contact of the molten metal,

injure the substance of the moulding,v and that will contract inl the act of congealing, so asito unite the two pieces by a deubly'tlaring rivet, E. Where the ornament is plated, the rivet lmay have the form shown at E,`

iig. 3. Among the various alloys applicable for this purpose, among the best so far tested is that known as Babbitt metal, say ten parts of tin, one of Copper, and .one5 regulus of antimony. The alloy may be melted in a ladle or by contact with a soldering-iron, and in the act of' settling draws the wood and met-al iirmly together. It will be seen that this contrivance, while cheaper than wood-screws, a'ords a much more perfeet and reliable air-tight joint, 'for the rivet E cannot work loose, as wood-screws are apt to do, and which in so doing afford avenues for the passage of air and gases, and-even should the ornament be broken 01T, the rivet E remaining in the metallic plate will prevent any leakage therethrough.

While selecting for lillustration the particular application for which my nventionwas specially devised, it is manifestly applicable to other substances thanthose above cited; for example, metallic ornaments may by this means be securely united to surfaces' ci aart-tremare, and vice versa.

I claim hereinA as new and of my irivention- Securing wooden or like objects' te metallic surfaces, 85o., by casting Babbitt or other metal of easy fusion into iiaring or branching holes C D and otherwise, as herein shown a'nd described.

In testimony ot' which invention I hereunto set my hand.

ROBERT HOWDON.
